PLUMBING TPIH'JTC} POST.

Application filed March 18, 1927:. Serial No. 176,423.

My invention relates to posts. for basin and sink stoppers, or the like, and more particularly. to. hollow plug postssuitable for attachring, to the stopper. L

()ne object of the invention is. the provision of a: siinplo,.strong,.one-piece, hollowpost adapted for attachment to a plumbing plug thus forming a complete stopper... Another object is the provision of a onespiece post which shall be water-tight; Still: a further object is the provision of: a. plug which. can beinexpensivelymanufactured with the min imam oi material. Other objects will be apparent upon consideration of this specifica tion..

The present invention comprises a unitary hollow post, formed from. a flat blank, and having certain projections and holes calculated especially to adapt the post for connection with the plug and with a ring for lifting the stopper. it post of this character is shown by Way of illustration in the accompanying drawings, in which-- V Figure 1 is an elevation of the hollow post showing its closing seam;

Fig- 2 is a bottom view of the post shown in Figure 1,

Fig. 3 is a top view of the post shown in Figure 1;

Fig". is another elevation of the post shown in Figure-l taken at right angles to the previous elevation;

Fig. 5" is a vertical section of the post taken on .the line 5-5 of Figure 1;

Fig. 6 is an assembled elevation of the entire stopper, the plug being shown in section;

Fig. 7 is a vertical section through a modified "form of post;

Fig. 8 is an elevation of a modified form of post constructed in accordance with the invention; and

Fig. 9 is an elevation of the stopper as sembly, the plug being shown in section, and the post being of the form illustrated in Fig. 8.

In the past it has been customary to manufacture posts for washbasin stoppers in solid form with appropriate flanges shaped upon them and a hole bored near the top for attaching the usual ring. Such posts, it is believed, have been unnecessarily heavy and have required an excessive amount of metal for their construction.

It has also been proposed to make plug posts of: hollow parts, but auxiliary parts have: beenqrequireid ina all casessbecause or the d-iflieulty of making the. hollow plug; waters tight. Suclr constructions are expensive: and easy to: get out of order.

According to the. present invention a one.- 00 piece ,.1:ioltowS plumbing. plug post is made water-tight. without association therewith of any additionall elements, and at. the: same timezthenecessary flanges are formed on the post;

In. the drawingsa unitar lumbin lu post 10IlS shown. This post formed f ioiii a single blank. and: is closed along asingle seam I]... It has. been found: that the seam ll canibe closed so'astorbezwaten tight- Thus the post has a water-tight closure.

Two: holes 12 and 13 are oppositely positioned near thetop of the plugi'oi"the-accommodationeztthe-usual; ring 14.-

An annular-flange 15 is shaped: on or uni.- tarily formed around the post a little distance below the holesl2 and 13; for a purpose which will: later appear. In the embodiment shown. in Figs. 81andl 9 this flange takes the form of a shoulder 15*, the: top'of; the post rising directly from: the flange edge without immediate reduction of diameten A second annular flange 16 is similarly shapedon the post. a. distance below the flange; 16 equal to the thickness of: the plug at. its center;. The 5 flange 16 is given in greater offset from the postthan the flange 151 for a! purpose: which will be pointed out later.

It has been found advantageous to close the bottom of the postby extending the metal downwardly in conical form from the circumference of the lower flange 16 to a point 17 That is to say, the closed lower end is formed on the lower flange. This conformation gives an exceedingly tight joint. 5 It is possible, however, to make the bottom closure of other than conical shape, for instance it may be flat as illustrated in Fig. 7.

In assembling this post 10 and plug 18 the post is inserted into the plug through a cen 00 tral hole 19 therein provided for the purpose. The post is inserted from the under side of the plug, the upper flange 15 being forced through the hole 19 in the plug and coming out on the upper side of the plug. Although this is accomplished most easily Where the embodiment illustrated in Figs. 8 and 9 is employed, no diificulty is experienced with the other'constructions. When the post is in place the ring 14: may be inserted through the holes 12 and 13, thus completing the assembly of the stopper.

A stopper is usually held in placebythe weight of the water above it, and-sometimes it is wedged in bythe person pushing on it.

' wedged,- and against the weight of the water The stopper is always removed, however, by a pull exerted upon the ring 14:. This pull must be of suflicient force .to remove the stopper from the position into which it is above the stopper. The flange 16 istherefore made larger than the flange so as to distribute this pull over a large area on the under side of the plug, and prevent the post being pulled out of the plug.

' 7 From what has already been said it will be realized that any water which may get by the ring 14 through the holes 12 and 13 into the post cannot escape from the basin becauseof the water-tight lower end of the post. No water, can escape from the basin varound the post for the plug material formscope of the invention. It is also to be noted ing the hole 19 surrounds the post and fits snuglybetween the flangeslo and 16 thus preventing leakage pastthe outside of the 0st. i V a It might be mentioned that the construction illustrated in Figs. 8 and 9 is in some respects preferable to those shown in the other figures. 1 It *ismore simple to manufacture, and when assembled gives the stoppera'neater appearance. I p

. In addition to the advantages of constructions according to the present invention which have already beenenumera-ted there maybe mentioned lightness, ease of. handling, andv economy :in shipping to distant points. f 1 1 Theform of post-illustrated and described and the stopper construction shown in the drawings are notto be taken as limiting the the material formingthe post, said end being water-tight. I

3..In-an integral hollow plumbing plug post, a closedlower endforming a flange upon said post, said end being water-tight.

1. An integral hollow plumbing plug post having. ahole adapted to receive a ring at itstop, an upper flange "formed around said post below the hole, and: a lower flange formed around said post, larger than said upper flange, in combination with a closedwater-tight lower end formed on said lower flange, substantially as described.

5. An integral hollow plumbing plug post having holes adapted to receive a ring at its top, an upper flange formed around said post below the holes, and a lower flange formed around said post larger than said upper flange, in combination with a conical closed water-tight lower end formed on said lower flange, substantially as described.

6. An integral hollow plumbing plug post having holes adapted to receive aring at its top, an upper flange formed around said post below the holes, the top of the post rising directly from the flange edge'without immediatereduction of diameter, and a lower flange formed around said post larger than said upper flange, in combination with a closed water-tight lower end formed on said lower flange, substantially as described.

- In testimony whereof I have signed my name to this specification.
